How are these Temperatures Measured?
Generally, temperature data depicting climate is usually given over a 30-year average in order to reduce short-term fluctuations and reveal better long-term trends in climate conditions.
This temperature data is taken from land-based thermometers, ocean buoys, ships, and satellites. These measurements are transmitted to weather stations and climate centers around the globe where they are processed, averaged, and analyzed in order to monitor the trends and create climate models.
Sea vs. Land Temperatures
The influence of nearby oceans or large water bodies significantly affects local temperatures:
- Ocean Influence: Coastal regions tend to have more stable temperatures, as large bodies of water absorb and release heat slowly. This often results in milder winters and cooler summers compared to inland areas.
- Continental Climates: Landmasses well away from large bodies of water tend to show greater extremes in temperature, having hotter summers and colder winters because of the absence of water as a moderating influence.
